Description

Technical Field

[0001] This invention relates to the field of sandwich feed production technology, and in particular to a compacted sandwich feed pelleting device. Background Technology

[0002] In the breeding of chickens, ducks, geese, and other poultry, necessary additives such as vitamins, microecological preparations, and active enzymes are added to the feed to improve the poultry's disease resistance and meat quality. In recent years, traditional Chinese medicine and beneficial enzymes have become increasingly widely used in the feed industry. To maximize the efficacy of these ingredients, sandwich feeds have emerged. Sandwich feeds encase concentrated feed, traditional Chinese medicine, and enzymes within roughage, minimizing waste during feeding. Once inside the poultry's body, the ingredients gradually disperse and exert their maximum effect.

[0003] In the prior art, Chinese patent document 2CN202552079U discloses a mold for feed processing, which utilizes a hollow mold head and a filling mold head, and connects the hollow mold head and the filling mold head from both sides of the mold base, simplifying the structure and allowing for external adjustment for ease of use and production of sandwich feed. Chinese patent document CN209573175U discloses a sandwich food forming device, which still uses a first extrusion channel 201 to encircle a second extrusion channel 303. Both of these solutions, in principle, first form the feed into a columnar shape, and then finally cut it to achieve pelleting. However, they also have significant drawbacks: firstly, the inner and outer layers of the feed pellets have different compression densities and insufficient compaction, leading to easy breakage of the pellets; secondly, existing equipment requires a subsequent cutting blade to form the final pellets; and thirdly, the pellets formed by the prior art are long, columnar shapes, which are prone to breakage, and the internal medicinal herbs and enzymes are easily wasted during consumption.

[0004] A compacted sandwich feed pelleting equipment is provided, which can fully compact the inner and outer layers of the feed pellets, greatly reducing the risk of feed pellet breakage. The pelleting process is one-time compression molding, which does not require the use of cutting blades. The pellets after compression molding are basically stable spherical pellets, which do not easily cause waste during feeding. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a compacted sandwich feed pelleting equipment, which effectively solves the problems of different densities of the inner and outer layers of the existing sandwich feed pellets, which easily cause pellet breakage, require the use of cutting tools, thus increasing costs, and the long cylindrical pellets that are easily broken during poultry feeding.

[0006] The technical solution includes a frame, an arc-shaped block fixed on top of the frame, a conical cavity on the outer circular surface of the middle part of the arc-shaped block, and a spiral rod that can rotate actively inside the conical cavity; there is a pelletizing template on both the left and right sides of the arc-shaped block, the template is a cone with the opening facing outward and the generatrix tangent to each other; each template has an outer shell fastened on the side away from the arc-shaped block, and the outer shell is fixed to the frame by a support rod; The template has a fixed shaft running through its center, which is fixed to the arc-shaped block. The template can rotate actively on the fixed shaft. The template has multiple sets of granulation units evenly distributed around its circumference. Each granulation unit includes a long groove located on the side of the template away from the outer shell. Each granulation unit contains multiple forming through holes, which are evenly distributed along the long groove. The end of each forming through hole away from the outer shell is a hemispherical recess, and the long groove connects the recesses in the same granulation unit. When the long grooves in two granulation units are engaged, a channel is formed. At this time, the multiple recesses in the two granulation units cooperate to form multiple complete spherical cavities. The outer shell contains a grinding wheel, which is rotatably mounted on a fixed shaft. When the upper end of the channel is aligned with the lower end of the conical cavity, the rotating screw can compress the material in the conical cavity and send it into the channel. At this time, the two templates rotate simultaneously, and the grinding wheel presses the material in the outer shell into the spherical cavity through the forming through hole. The material in the outer shell enters the spherical cavity and completely wraps and compacts the material in the conical cavity, ultimately forming spherical particles.

[0007] Furthermore, the spiral rod includes a vertical shaft, which is coaxial with the conical cavity. A spiral blade is fixed at the lower end of the vertical shaft. The outer edge of the spiral blade is tangent to the inner wall of the conical cavity. A mounting plate is fixed at the upper part of the conical cavity. A first motor is connected to the upper end of the vertical shaft and is fixed on the mounting plate.

[0008] Furthermore, the molded through hole has a funnel-shaped opening at one end near the outer shell.

[0009] Furthermore, the hemispherical recess and the molded through hole it is located in have an eccentric structure.

[0010] Furthermore, the outer edge of the template is configured with a toothed structure, and a second motor is fixed on one of the outer shells. The second motor is connected to a gear, and the rotation of the gear can drive the two templates to rotate simultaneously.

[0011] Furthermore, the arc-shaped block is fixed together with the outer shell by multiple connecting rods.

[0012] Furthermore, a feed inlet is provided on the upper side of the outer shell.

[0013] Furthermore, the lower end of the roller is tilted forward, and the lower end of the template rotates from front to back.

[0014] The invention has a clever structure that allows the inner and outer layers of the feed pellets to be fully compacted, greatly reducing the risk of feed pellet breakage. The pelleting process is a one-time pressing and forming process that does not require the use of cutting tools. The pellets after pressing are basically stable spherical pellets, which do not easily cause waste during feeding. Attached Figure Description

[0027] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Depend on Figures 1 to 12The present invention includes a frame 1, an arc-shaped block 2 fixed on the top of the frame 1, a conical cavity 3 formed on the outer circular surface of the middle part of the arc-shaped block 2, and a spiral rod 4 that can rotate actively inside the conical cavity 3; a pelletizing template 5 on each side of the arc-shaped block 2, the template 5 being conical with the opening facing outward and the generatrix tangent to each other; a shell 6 is fastened to the side of each template 5 away from the arc-shaped block 2, and the shell 6 is fixed to the frame 1 by a support rod; The template 5 has a fixed shaft 7 running through its center, which is fixed together with the arc-shaped block 2. The template 5 can rotate actively on the fixed shaft 7. The template 5 has multiple sets of granulation units evenly distributed around its circumference. Each granulation unit includes a long groove 8, which is located on the side of the template 5 away from the outer shell 6. Each set of granulation units contains multiple forming through holes 9, which are evenly distributed along the long groove 8. The end of the forming through hole 9 away from the outer shell 6 is a hemispherical pit 10. The long groove 8 connects the pits 10 in the same granulation unit. When the long grooves 8 in two granulation units are engaged, a channel is formed. At this time, the multiple pits 10 in the two granulation units cooperate with each other to form multiple complete spherical cavities. The outer shell 6 contains a grinding wheel 11, which is rotatably mounted on a fixed shaft 7. When the upper end of the channel is aligned with the lower end of the conical cavity 3, the rotation of the spiral rod 4 compresses the material in the conical cavity 3 and sends it into the channel. At this time, the two templates 5 rotate simultaneously, and the grinding wheel 11 presses the material in the outer shell 6 into the spherical cavity along the forming through hole 9. The material in the outer shell 6 enters the spherical cavity and completely wraps and compacts the material in the conical cavity 3, ultimately forming spherical particles.

[0029] In order to achieve the active rotation of the screw rod 4, the screw rod 4 includes a vertical shaft, which is coaxial with the conical cavity 3. A helical blade is fixed at the lower end of the vertical shaft. The outer edge of the helical blade is tangent to the inner wall of the conical cavity 3. An mounting plate 12 is fixed at the upper part of the conical cavity 3. A first motor 13 is connected to the upper end of the vertical shaft and is fixed on the mounting plate 12.

[0030] In order to make the material pressing of the roller 11 smoother, the forming through hole 9 is funnel-shaped at one end near the outer shell 6.

[0031] To ensure that the material inside the outer shell 6 can completely or mostly enclose the material that has been pressed into the channel, the hemispherical recess 10 and the forming through hole 9 are eccentrically arranged.

[0032] In order to enable the two templates 5 to rotate synchronously, the outer edge of the template 5 is set with a toothed structure, and a second motor 14 is fixed on one of the outer shells 6. A gear 15 is connected to the second motor 14. The rotation of the gear 15 can drive the two templates 5 to rotate simultaneously.

[0033] In order to install the arc-shaped block 2, the arc-shaped block 2 is fixed together with the outer shell 6 by a plurality of connecting rods 16.

[0034] The outer shell 6 has a feed inlet 17 on its upper side.

[0035] In order to maximize the function of the rolling wheel 11, the lower end of the rolling wheel 11 is tilted forward, and the lower end of the template 5 rotates from front to back.

[0036] As can be seen from the above, in this scheme, when the long groove 8 of the granulation unit is aligned with the lower end of the conical cavity 3, the multiple pits 10 in the two granulation units on different templates 5 cooperate with each other to form multiple spherical cavities. At this time, the multiple spherical cavities and channels form a structure similar to "candied hawthorn". During granulation, the material in the conical cavity 3 first enters the channel, and then the roller 11 squeezes the material in the outer shell 6 into the spherical cavity through the forming through hole 9. In this way, the material in the outer shell 6 completely wraps the material in the conical cavity 3 and compresses it into a spherical shape.

[0037] It is worth noting that the grinding wheel 11 in this invention has the same function as that of a traditional flat die feed pellet mill. The template 5 drives the material to rotate, and the material is forcibly pressed into the forming through hole 9 when passing through the grinding wheel 11. As for how to maintain sufficient raw material in the grinding wheel 11, the method of the ring die feed pellet mill in the prior art can be referred to. Of course, there are many ways to ensure sufficient material in the grinding wheel 11, which will not be elaborated here. Bearings are installed between the grinding wheel 11 and the fixed shaft 7, between the template 5 and the fixed shaft 7, and between the outer shell 6 and the outer edge of the template 5. All bearings are dustproof bearings.

[0038] In use, the inner layer materials, such as concentrated feed, Chinese medicinal herbs, and biological enzymes, are thoroughly mixed and poured into the conical cavity 3. The outer layer materials, which are mixed with roughage and other substrates, are poured into the two outer shell cavities 6. The first motor 13 is started, and its rotation, via the screw rod 4, squeezes the inner layer materials downward and into the channel formed by the two long grooves 8 on its lower side. Then, the second motor 14 is started, and its rotation, via the gear 15, drives the two templates 5 to rotate simultaneously. When the material passes through the grinding wheel 11, the grinding wheel 11 squeezes the material into the shaping through hole, and finally into the spherical cavity, encapsulating the inner layer materials. The first motor 13 and the second motor 14 work intermittently to complete the working cycle, thus realizing sandwich pelleting.

[0039] As can be seen from the above, if the axis of the conical cavity 3 is parallel to the axis of the grinding wheel 11, the inner material may not be able to enter the outermost spherical cavity, that is, sandwiching failure may occur. To avoid this, the axis of the conical cavity 3 and the axis of the grinding wheel 11 can be set at an angle. Figure 10In the state shown, the axis of the conical cavity 3 and the axis of the grinding wheel 11 are spatially non-intersecting and non-parallel, and the angle between the axis of the conical cavity 3 and the horizontal plane is smaller than the angle between the axis of the grinding wheel 11 and the horizontal plane. Thus, because the inner layer material is compressed and strip-shaped, it can pre-enter between the two long grooves 8 before they fully engage. When the inner layer material reaches the grinding wheel 11, the outer layer material is squeezed into the spherical cavity to form a sphere, and the inner layer material is wrapped by the outer layer material. As the two templates 5 continue to rotate, the gap between them increases, and the newly compressed spherical sandwich feed pellets fall off. If necessary, a vibrating motor can be installed at this point to facilitate the falling of the sandwich feed pellets.

[0040] During the process of the outer material entering the spherical cavity, since the shaping through hole and the hemispherical pit 10 are eccentrically set, the outer material "pushes" the inner material to break when it enters the spherical cavity through the shaping through hole. The broken part of the inner material is tightly wrapped by the outer material, achieving the purpose of sandwiching.

[0041] In use, this invention employs two materials that are pressed separately, and then the inner and outer layers are pressed together to form a pellet. This ensures that the inner and outer layers of the pellet are fully and effectively compressed, greatly reducing the risk of feed pellet breakage.

[0042] Because the inner layer material enters the spherical cavity first, and then the outer layer enters the spherical cavity, the outer layer material can completely wrap the inner layer material, which effectively ensures that the concentrated feed, Chinese medicinal materials and biological enzyme additives can exert their maximum efficacy and greatly improve feed utilization.

[0043] The invention has a clever structure that allows the inner and outer layers of the feed pellets to be fully compacted, greatly reducing the risk of feed pellet breakage. The pelleting process is a one-time pressing and forming process that does not require the use of cutting tools. The pellets after pressing are basically stable spherical pellets, which do not easily cause waste during feeding.
